Primary outcomePrimary: Speech Reception Thresholds (SRT) Assessed in Spatially Separated Speech and Noise (S0Nrearhalf) — -10.34; -6.04; -4.30 dB SRT
Summary
The clinical study aims to investigate acceptance, actual-use usability and speech performance with a new behind-the-ear sound processor (model number: CP1110) system, compared with the commercially available Nucleus 7 Sound Processor (model: CP1000) system, with particular focus on the acceptance of and satisfaction with a noise reduction feature in the Automatic Scene Classifier 'SCAN 2'.
